Hi Bill,

The revision number parameter is just something that we add to the CSS URL so that after an administrator changes a look and feel setting for the site, the browsers grab the updated one instead of relying on a cached copy. The revision on the URL doesn't affect how the stylesheet's content.

In general, feel free to add new styles. However, keep in mind that changing existing GWT styles will affect all GWT apps in the software. I think that in most places we want GWT text areas to line wrap, so it might make sense for you to add a new style to handle non-wrapping text areas.

Thanks,
Josh
